Full featured Z-Wave thermostat for use with HomeSeer and other systems. Very simple to install: This unit is designed to replace virtually any existing thermostat without the need to run additional wires! The newest 2GIG thermostat is thinner, has longer battery life and improved Z-Wave range, compared to the original CT30 design.

As with the earlier model, the CT100 may be powered solely on batteries or via external "C-wire" power. This makes it a "drop in replacement" for virtually any thermostat it might be replacing in a typical home. At under $100, this is a great little unit!
